Key points of the planning were elaborated from 4 perspectives of spatial structure, traffic organization, spatial sequence and plant configuration to discuss spatial configuration of ecological landscapes on the fringes of Chengdu City, then further improve functions of ecological landscapes and quality of ecological environment, and put the concept planning into the construction practice of urban fringes.展开更多

Therefore, carrying out assessments of land and identifying a suitable zone for human habitats were very important. This research creates the territorial suitability assessment and function zoning conceptual model in the earthquake-stricken area, and the new methods of the territorial suitability evaluation system were used to divide the spatial functional zones of the earthquake stricken area, which provide a theoretical guidance and decisionmaking basis for the reconstruction of the disaster area. The results showed that:(1) The Jiuzhaigou earthquake-stricken area comprises of an ecological area that has a high level of importance to the ecosystem. In the earthquake-stricken area, 65% of national land is at an altitude of 3000-4000 m, and therefore not suitable for a high level of intensive reconstruction, but reconstructed in an eco-friendly manner.(2) The zone suitable for reconstruction comprises mainly of the river valley and the flat terrain of western parts. The land with low suitability is mainly located on steep terrain, such as highmountains and low gullies. The geographic and geomorphic conditions limit the spread of a suitable reconstruction zone.(3) The earthquake-stricken area mainly comprises of a tourism industry gathering area, population gathering area, agriculture and animal husbandry development area, and ecological preservation area with areas of 76 km^2, 44 km^2, 1591 km^2 and 7512 km^2, respectively. Scientifically zoning the reconstruction areas using scientific evaluation may provide guidance for the location of reconstruction sites.展开更多

The questionnaire was designed to evaluate socirydeweraphic background, the subjects' nutrition knowledge, and the support systerns for geriatric nutrition. Fasting venous blcod was colected for the analysis of biochemical parameters. Blood pressure, bene mineral contents (BMC), body weight (BW) and they height (BH) were measured at the same time. Only 49. 7% of the subjects correctly an swered four basic questions on nutrition. Food patterns for the elder1y were simple and modest. Several nutrition-related disorders for the elderly were including high systolic bbo pressure (44. 6 % ), hyPertriglyceridemia (25. 9 % ), high diasto1ic blood pressure (25. 1% ),obesity (24. 5% ), high PBG (20. 6% ), emaciation (19. 9%), high FBG (17.9%) and osteoporosis (16. 8%). These data indicate that the support systems for the geriatric nutrition will have to be improved.展开更多
